Distal mucocolpos and proximal hematocolpos secondary to concurrent imperforate hymen and transverse vaginal septum.

A 12-year-old girl had cruciate incision of imperforate hymen draining a large mucocolpos. Her symptoms did not abate thereafter, and 3 months later a transverse vaginal septum was diagnosed. This was perforated and dilated under ultrasound (US) guidance draining a large hematocolpos. Results of examination under anesthesia after 3 months was satisfactory, and she has had normal periods in follow-up for 9 months. Imperforate hymen and transverse vaginal septum are known causes of mucocolpos and hematocolpos. However, the concurrent occurrence of the two abnormalities is unique.
